DEMOUN TABLE RIM.

Be it known that I, Areas L. PUTNAM, a c i ti zen of the United States of America, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in De mountable Rims, of which the following is a specification, reference being had therein to the accompanying drawings. v 4

The invention relates to demountable rims for vehiclewheels and is particularly adapted for use in connection with wheels having large sizes of tires, such for instance as are used upon trucks. It is the object of the invention to facilitate mounting and dethe rim, and also the mounting and demounting of the rim in relation to the wheel. end the invention comprises the construction as hereinafter set forth. a i In the drawings: Figure l is a cross section through a wheel t5 which my improved ppl r a Fig; 2 is a side elevation thereof; Fig. 3 is an enlarged cross section of the securing means for the demountable rim; Fig. 4 isa similar view showmg a 'modified construction,

My invention 18 applicable to various es of vehicle wheels, but as shown is applied to a metallic wheel of the dished disk t in which A is the hub, B is the dishe 'disk body ofthe wheel and C are E of the disk is arrange bolts for securing the disk to the the hub. The eripheralortion d in the p ane of rotation and in connection with a clamping clamping flange D of e demountable rim is formed in two lane of rotation and at one side of the fe ly ortionof the wheel body. These sections and F inwardly-extending anrinlg F forms in efi'ect a fellyof the wheel.

ded with To thisdemountable rim is Specification of Letters Patent. Patented Feb, 25, 1919.

Application filed July 18, 1917. Serial No. 180,257;

the nuts J in relation to the dcmountable run so that they may not be lost during exchange oi runs. On the other hand, it is I desirable that the nuts should be successively engageable with and 'diseugageable from their respective bolts and without interference with each other. I therefore form the nuts J with cylindrical portions K longitudinally adjustable in the apertures in the flanges G and G and provide a retaining shoulder K at the innerendof the portion Ix. This shoulder or enlargement of diam- "eter is suflicient to prevent the nut from being detached from the flange G. but the apertureL in the flange G is sufliciently large for 'the passage of said shoulder, thereby permitting the flanges G and G to be separated from each other, the nuts being retained by the flange G. The amount of longitudinal adjustment of the portions K in the fiange G is sufficient for the complete screwing on to or screwing off from the belt- I, and to. provide space for receiving this portion K when-the nuts are'tightened the ring F is formed with embossed port-ions M for receiving both the bolts I and portion K,

of the nut.

In mounting the tire upon the rim the to permit of separating the sections F and F The tire is then placed upon the section F and the section F retngaged therewith and secured bv a ain clamping the bolts and nuts H andH'. o mount the rim upon the wheel it is slipped over the folly portion of the wheel until the flanges G and G lie adj accnt to the portion while the nuts H are passed through registering apertures in said portion E. The nuts J are then successively secured upon the bolts I, which will draw the flange G against the portion E on one side thereof and thering F against the opposite side thereof.- When all of the nuts are thus secured the rim will be firmly at-' are rov'i p tached to the wheelandvwill retain its firm engagement therewith until it is necessary to make another replacement.

As shown in Fig. 4, a demountable rim is applied to a wooden wheel in which N is the wooden felly, O the spokes and P the melallic rim secured to thefelly and having the flange Q, on one side thereof. The demountable rim is applied to this wheel by placing the flanges of the complementary I rim sections adjacent to the flange Q and senular flanges G and G lying adjacent to. each other and secured at intervals by clamping bolts H. To secure the mm to the wheel I a second series of bolts I are arranged intermediate the bolts H, said bolts I being se- 50 cured to the telly portion of the wheel and preferably to the rim F and extending throu h apertures in the flanges G and G J designates nuts for engaglng the bolts I- and clamping the flanges G and G against 55 the felly portion E. It is desirable to retain wheel body curing them by bolts and nuts in the manner previously described. The telly and flange Q are cut-away at R to receive the clamping bolts and nuts which secure the rim sections to each other.

The term wheel body as used in the preceding description and in the following claims is considered to denote a structure which may either include a feliy or omit the same.

\Vhat I claim as my invention is:

1. The combination with a wheel body, of a demountable rim formed in sections separable in a plane at one side of the wheel body and provided with adjacent inwardlyextending flanges, a series of clamping bolts for securing said flanges to each other, an

intermediate series of clamping bolts for securing said flanges to the wheel body, and nuts firmly attached to the rim cooperating with the last-mentioned bolts and adapted to be successively screwed on and off the same.

2. The combination with a wheel body, of

a demountable rim-formed in sections sepa-- rable in a plane at one side of said wheel body and provided with inwardly-extending adjacent flanges, a series of bolts for securing said flanges to each other, an intermediate series of bolts secured to said wheel body engaging rim flanges intermediate the clamping bolts therefor, and a series of nuts for cooperating with the last-mentioned bolts, said nuts being permanently mounted on one of the flanges 0 body and provided with adjacent flanges, a, series of bolts for securing said flanges to each other, a seriesof bolts secured to said intermediate the bolts of said rim, a series of nuts for cooperating with said wheel body bolts, said nuts being provided with cylindrical portions slidably engaging apertures in the flanges of sai' rim sections and a shoulder for limiting the sl1d- "0' ing movement to' retain engagement of the nut with one of said flanges permitting of disengagement from the ot er of said flanges.

4. The combination with a wheel body, of

said rim sections and adapted to be successlvely screwed on and mousse a demountable rim formed in sections separable in a plane at one side of said wheel,

body and provided with adjacent inwardly;

, extending flanges, a series of bolts for securing said flanges to each other, 'a ring upon l bossed portions, bolts secured within the embossed ortion of said ring, and nuts hax ing cylindrical portions longitudinally-slidably engaging one of the flanges of said rim sections and adapted to be secured on to said bolts within the embossed portions of said rmg. j l

5. The combination with a wheel body, of a demountable rim formed in sections separable, in a plane at one side of said wheel body and provided with adjacent flanges, a series of bolts secured to the wheel body, a series of nuts for cooperating with said bolts said nuts .having cylindrical portions slidably engaging apertures in the flanges of said rim sections, and a shoulder for limitment of the nut with one of said flanges permitting of disengagement from the other of said flanges.

, ing the sliding movementto retain engage- 6. The combination with a wheel body, of v a demountable rim formed in sections sepa rable in a plane at one side of said wheel body and provided with adacent inward yextending flanges, a ring upon the opposite .side of the wheel body from that of said flanges, said ring having embossed portions, bolts secured within the embossed portions of said ring, and nuts permanently engaged with one of said flanges passing through the flanges and through the wheel body for en agement with said bolts.

The combination with a wheel body, of a demountable rim formed in sections sepa- 'rable in a plane at one side of said wheel body and provided with adjacent flanges, a series of bolts secured to the wheel body, a series of nuts for cooperating with said bolts, said nuts fitting loosely in apertures in one of said'flanges and being restrained against disengagement from said apertures, said nuts having an axial play in said apertures to permit of their enga ement with and disenga ement from the bolts without entailing t e movement of said a ertured flange.
